• This invention relates to an inflatable boom.
• an inflatable boom the boom being elongate and being provided with at least one line by means of which the boom can be launched from a watercraft into surrounding water.
• Such an inflatable boom may be used as a life-saving device; in such a case the boom would be launched from the watercraft into the surrounding water.
• the boom could be launched in the general direction of the man overboard; the elongate nature of the boom means that the man overboard has a larger target to aim for.
• the boom would be at least 20 feet long but typically 100 feet long.
• the line may be provided with a projectile, typically at one end thereof.
• the projectile may be arranged to be launched from a suitable launcher, such that launching the projectile draws the boom in the direction of launch, typically into the water.
• the projectile may be ballistic, in the sense that its movement is unpowered other than the momentum imparted to it by the launcher, or may be self-propelled. Typically, the projectile would have significantly greater mass than the line. Such a projectile can be considered "weighted" .
• the boom may have an unlaunched state and a launched state, which the boom assumes after launch, the launched state of the boom occupying relatively more space than the unlaunched state.
• the launched state may comprise an inflated state, whereas in the launched state the boom may be less inflated, typically substantially uninflated.
• the boom may be provided with a housing in which it is housed in the unlaunched state. Typically, it would not be possible to house the boom in the housing in the launched state. In a preferred embodiment, in the unlaunched state, the boom is folded or wound into the housing so that the length of the housing is significantly less than the length of the boom in the launched state.
• Such a boom is very useful as it allows for compact storage on board the craft, but allows for a long inflated boom to be quickly provided on the water's surface adjacent to the man overboard.
• the boom may comprise an elongate hollow tube. It will typically comprise an inflation system which is arranged to inflate the boom when it assumes the launched state. Typically this would be when the boom hits the water, or when it is launched. In the former case, the inflation system may be arranged to determine when it hits the water's surface and on that determination inflate the boom.

In the former case, the inflation system may be arranged to determine when it hits the water's surface and on that determination inflate the boom.
• the inflation system is activated by action of launching.
• Midair inflation has been found to be particularly convenient and to provide repeatable results with the aiming and placing of the boom.
• the inflation system may activate due to the change in kinetic energy or momentum of the boom or the inflation system.
• the inflation system may comprise a mass separated from an activator in the unlaunched position, but which is able to move to activate the activator when the boom is launched.
• the inflation system may therefore comprise a spring normally acting to separate the mass and the activator, the change in momentum of the remainder of the inflation system relative to the mass causing the mass to move towards the activator against a biasing force due to the spring.
• the activator may comprise a valve, or a piercing member such as a needle arranged to pierce a reservoir of compressed gas on activation by the mass.
• the boom may be provided with a plurality of guide lines. These are typically elongate flexible members attached at one end to the inflatable boom, the distal end typically being retained at the launching position. In one embodiment, lines are provided connected at each end of the boom and at one third and two thirds along the length of the boom.
• the boom can be steered to meet the man overboard, and to guide the boom back to the craft once the man overboard has grasped the boom.
• the boom is preferably provided with at least one light source, which illuminate in the launched state of the boom. By lighting the boom, a man overboard has more chance of finding the boom in dark or choppy seas.
• the light source is internal to the boom, with at least one window in the wall of the boom allowing the transmittal of light from therewithin.
• At least part of the internal wall of the boom may be reflective; preferable the wall is at least 90% reflective. This enables the light from the light source to be reflected down the internal walls of the boom when inflated, in a manner similar to an optical fibre.
• refractive surfaces or media may be provided within the boom in order to transmit the light from the light source to the windows.
• the boom may be partially transmissive, such that the boom "glows" when the internal light source is illuminated.
• the light source may be provided with a pressure-activates switch, such that an increase in pressure consequent upon inflation of the boom activates the switch and hence causes the light source to illuminate.
• the light source may be provided with an impact activated switch, such that impact of the boom on the water's surface activates the switch and causes the light source to illuminate.
• slits may be provided through the boom so that a man overboard can pass himself therethrough to secure himself to the boom.
• the boom of the present invention can be used not only to rescue men overboard, but to surround oil spills and the like.
• the boom can be projected onto the water's surface around an oil spill, and then guided around the oil spill to contain it.
• the boom may comprise a skirt, which in use in the launched state depends from the boom downwards below the water's surface.
• the skirt depends at least 9 cm below the boom.
• the boom may also be provided with a skirt which extends upwards above the boom in the launched state. This may extend at least 9 cm above the boom.

• the boom comprises a length - at least 20 feet - of airtight hollow tubing, typically formed of polyurethane or other suitable material. It should be of relatively high strength, so that it can bear the weight of a man overboard in use. As such, the strength may be engineered into the fabric of the tube itself, or the tube may be provided with strengthening on the tube walls. However, the material should be generally lightweight, for convenience of storage and use.
• an inflation system 3 This comprises a supply of compressed gas (air, for example) that is released when the boom is launched.
• the inflation system can be seen in more detail in Figure 7 of the accompanying drawings. It comprises a reservoir of compressed gas 20 having a seal 21. Should this seal 21 be ruptured, the compressed gas can escape into the body of the boom 1.
• the means by which this occurs is an activation needle 22. This is normally held away from the seal 21, but can be activated by a mass 23 of the form of a ball bearing. This ball bearing is separated from the activation needle by a spring 24.
• a line 4 At the other end of the inflatable boom 1 there is attached a line 4 by means of a D-ring (not shown) .
• the line connects the boom 1 at one of the line's end to a projectile 5 at the distal end of the line 4.
• This projectile 5 is suitably heavy that it acts as a ballistic projectile (overcoming a substantial amount of air resistance) when launched. Typically, it would have a mass of about 1.5 kg.
• the projectile 5 is fitted within a launcher 6. Whilst any suitable launching technology can be used, in the present embodiment a compressed gas launcher is used. In this, a user aims the launcher 6, then presses a trigger 7. This releases a charge of compressed gas held within the launcher 6. The increase in volume of the compressed gas as it is released launches the projectile 5 from the launcher 6 in a ballistic fashion.
• FIG. 2a a man 10 has fallen overboard off ship 12. He will henceforth be referred to as the "man overboard” .
• a rescuer 11 is alerted to this fact, and picks up the launcher 6, dislocating it from its storage area if necessary. He aims the launcher over the head of the man overboard 10. For convenience's sake, the launcher is should-mounted.
• the rescuer 11 fires the launcher 6 using the trigger 7. As the projectile is launched from the launcher 6, it draws the boom 1 from its housing 2 in the general direction of the man overboard 10, as shown in Figure 2b. A range of 30 to 80 metres is possible.

• the system is designed to be lightweight as possible as to be launched as far as possible with the container designed to be a stowage system.
• the unit is designed for being used in a shoulder launched projectile system as well as a static mounted system for longer distance deployment, or possibly a remote controlled fixed mounted launcher as well as a portable manually deployed container.
• the above-described actuation system is stowed in the hold of any vessel or area on shore or anywhere by water, etc. A situation arises where the unit is required to be used.
• the launcher is already charged independently or in conjunction with this apparatus. For example in a man overboard scenario there is a requirement to rescue and individual from the water.
• the rescuer goes to the stern of the ship (in this embodiment) opens the box in which is stowed all of the connected apparatus above which is charged and ready to go.
• the operator opens the box, removes the projectile, inserts the projectile into the charged launcher, steps behind the launch box (in this example) , which is on the deck of the vessel and fires the projectile over the head and behind the individual in the water.
